To all whom it may concern:

Be it known'that I, (,)soAn F. PETERSON, citizen of the United States,residing at Brockton, in the county oi Plymouth and State ol'llrlassachusetts, have.y invented certain new and useful Improvements inCalk- Plates for Horseshoes; and l do hereby de* clare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains `to make and usethe same.

The present invention relates to detachable ca k plates for use inconnection with horse shoes.

The object of the present invention isto produce a strong detachablecalli plate which may be readily attached to a shoeor detached therefromwhen in position upon an animals hoof, and one which requires no'specialor peculiar construction of -shoe to enable the calk plate to beattached thereto.

With the above object in view, the resent invention consists in the im)roved ca c' plate hereinafter described and claimed.

The present invention will be clearly une 'derstood from an inspectionof the accom-4 panying drawings, in which- Figure 1 is an inverted planview of a horse shoe with the detachable calli plate secured in positionthereon; Fig. 2 isa side elevation ol the Ashoe and calli plate shown inposition shoe and calk late as viewed fromthe righthand side of lgig. 2;and Fig. 4 is asection taken on line 4 4, Fig. 1, but inverted.

In said drawings, a horse shoe 1 of coinmon and well known construction,is shown having a toe calk 2, heel calks 3 and 4, and anl upwardlyprojecting ange 6 which rests against the front portion of'the hooi'.@verlying the shoe 1 isa c'alk plate S composed of a frame ofsubstantially the same contour as the shoe, Aand Ahaving at its toeportion anges 10 and 11 which are bent upwardly and inwardly to embraceopposite sides of the toe portion el the shoe 1. Said ilanges 10 and 11are located upon opposite sides of the toe calk 2, and sul'licient spaceis provided between the inwardly extending portions of saidfla'n es andthe op osing face of the toe calli to a low the calk p ate to be readilyapplied to and removed from the shoe. A cross-bar 12 is provided at theheel portion of the calk plate, and is increased in thickness at itscentral portion to form a boss 14 which is threaded 'to' receive a bolt15. A'yoke 18 spans the heel portion of the shoe across the heel callas3 and 4i, and is gular anges 19 and 20 which are adapted to rest againstthe outer ends and sides of the calks 3 and 4 respectively Said yoke isproprovided with anvided with a boss 22 through which the bolt 4,- 15passes. The said boss may be provided with a transverse groove 24, whichis adapted to receive a corresponding projection 25 on the inner face ofthe head 26 of the b .t 15. The purpose of this groove and projection isto prevent the bolt 15 from backing up when the yoke 18 has been clampedagainst the shoe.' Removably secured to the callrL plate S are aplurality of calks 30, which in the present instance are shownf asformed with cylindrical body portions 31 and conical points 32;

In the construction above set forth it will belnoted that the means forsecurin the calli plate to 'the shoe, consisting ol the flanges 10 and11, the bolt 15, and the clamping yoke 18 are all mounted upon or e1n'bodied in the calk plate and are adapted to cooperate with a horse shoeoiordinary construction and shape. Thecalk plate therefore does not reuire the use of an s ecial q y P or peculiar construction of horse shoebut can be readily applied to, or vremoved from, an ordinary shoe whileon the hoof ol a horse. lt will also be noted that when the bolt 15 istightened against the yoke 18, the calk plate is drawn toward the rearof the shoe,` and is centered by the flanges 10 and 11, and is 4securelvclamped in position by the flanges and the yoke. The flanges 10 and 11engage and extend over the toe portion of the shoe while the yoke 18engages and extends over the heel portion of the shoe so that the calliplate is securel and rigidly held against movement in any irection'par--allcl to the shoe and is absolutel" prevented from moving in adirectionat rig the shoe. v

The nature and scope of the resent invent angles to tion having beenindicated an the preferred t'orni ol" the invention having been speciic`ally described, what is claimed ist* `1. A detachable calk plate forhorse shoes,-
